Pan Pulp Prepared by Precipitation Method

LIU Yong-le,YOU Xiu-lan,LIU Zhao-feng,HU Zu-ming,SHEN Xin-yuan (College of Material Science and Technology,Donghua University,Shanghai,200051)  
PAN pulp with high specific surface area has been obtained by precipitation method. Effects of parameters during precipitating process on the properties of PAN pulp have been studied. The surfaces of the resultant pulps were observed by scanning electron microscope and specific surface areas were measured by BET method. It has been found that increasing the shear rate and prolonging the shear process, elevating the temperature of PAN solution and coagulation were favored to prepare PAN pulp with high specific surface area.
